Created a replica of a drying rack arm from a Indoor Clothes Drying rack from amazon, of this sort: https://a.co/d/4z61Uwy
Designed it so it could fit left or right. My particular drying rack, the bottom arms are longer than the middle and top arms. This model fits the top and middle arms. Althought it should be possible to slightly modify it to fit whatever dimensions needed. It was designed in OnShape, I'll leave the link for that and the STEP file available for download for your remixing pleasure!
